My focus is on reliable operations, sound technical decisions and careful implementation: virtualisation, server platforms, storage, backup and monitoring.</p> <p>I take an analytical, structured approach, quickly familiarise myself with existing environments and explain technical issues clearly. Beyond solving the immediate problem, I prioritise useful documentation and solutions that remain sustainable in day-to-day operations.</p> <p>Depending on the project, I provide second- and third-level support, take responsibility for design and implementation, or support migrations and technical changes from the initial assessment through to handover.</p> https://stefan-gold.com/en/profile/ Mon, 01 Jan 0001 00:00:00 +0000 https://stefan-gold.com/en/profile/ <figure class="profile-photo"> <img src="https://stefan-gold.com/images/stefan-gold.jpg" width="720" height="900" loading="lazy" decoding="async" alt="Stefan Gold"> </figure> <h2 class="relative group">Stefan Gold <div id="stefan-gold" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#stefan-gold" aria-label="Anchor">#</a> </span> </h2> <p><strong>Senior IT Infrastructure Consultant</strong><br> Virtualisation · Linux · Storage · Backup · Data centres</p> <p>I support organisations with demanding infrastructure projects and the reliable operation of business-critical platforms.
